Fig. 2A. 30-year-old woman with mammographically dense breasts and
strong family history of breast cancer. Contrast-enhanced sagittal spoiled
gradient-echo (SPGR) MR image shows no abnormal enhancement at index site that
prompted recommendation for MR imaging (not shown). Solitary focus of
enhancement (arrow) is seen. Biopsy was recommended because of strong
family history of breast cancer and irregular shape of incidental focus.
Patient did not return for 6 months.
